说明： ER316 焊丝主要成分是18Cr-12Ni-2Mo。配用SJ601不锈钢碱性烧结焊剂，其焊缝金属具有良好的力学性能和抗晶间腐蚀性能，焊缝抗裂性良好；具有不增C，且Cr、Ni烧损小等特点。因合金含量高，耐腐蚀性能优良。
用途： 长应用于石油化工、化肥、尿素生产或储存设备，如06Cr17Ni12Mo2（SUS316）等材料的焊接。
Instructions:  The ER 316 welding stick consists mainly of 18Cr-12Ni-2Mo.It coordinates with the stainless steel alkaline sintered flux SJ601 .It’s welding line metal has good mechanical properties and resistance ability to intergranular corrosion and crack. It would not increase Si or C and would burn little Cr and Ni. Due to a low content of carbon, it has excellent inoxidability.
Use:  It’s usually used to weld materials in petrochemical industry and production and storge facilities of fertilizer or urea, such as 06Cr17Ni12Mo2 (SUS316)

注意事项：
保护气体：注意保护气体的纯度，混合气配比**Ar+1~3%O2。TIG采用纯Ar。
气体流量：20~25L/min。
干伸长度：15~25mm。
将焊接部位的锈层、湿气、油污、灰尘等确实除净。
室外焊接时，当风速大于1.5m/s应采取适当的防风措施，以防发生气孔。
以上建议仅供参考，在具体造作中以现场情况为准。必要时先进行工艺评定再确定焊接方案。
Cautions:
Consumers should pay attention to the shielding gas.The recommended gas mixture ratio is Ar and 1~3%O2.The TIG should use pure Ar.
The gas flow rate is 20~25L/min.
The elongation length is 15~25mm.
The rust scale, moisture, oil stain and dust in the welding position should be definitely cleaned.
When welding outdoors with over 1.5m/s wind speed,appropriate wind proof measures should be taken,in case of air vent.
The suggestions above are for reference only.The specific operation is subject to the actual situations.If necessary, consumers should evaluate the technical qualification before determining the welding scheme.
